Recently I have felt like showing my dick (5” soft, 6.5” erect) to my friends. For example, at the urinal I stand further back so people can see my dick, or I get an urge to piss in front of my friends.
I heard we have a school trip coming up and I’m excited for my friends to see my 5” soft cock in the showers, etc.
One of the “popular kids” in my school saw me at the urinal and told a few people about my big penis - I was overjoyed.

This has only been happening recently as my cock started growing. Is it normal or a puberty-related thing, or does it mean something else?
